I mean, you can't deny Marvels marketing strategy is good. But when you look at it, Marvels Civil War marketting strategy isn't all that different from DC BvS marketing strategy.
What didn't matter was the marketing. What matters is the word of mouth at this point. And DC's word of mouth was bad thus the film suffered despite, lets be honest, rather fantastic marketing. I mean that one trailer where we saw Batman take down all those men. The film looked like it'd be a massive hit. But it ended up being less than the studio wanted.
With Marvel they slap their name in there and a cameo from an Avenger and the film is guaranteed success from the start. It's not a fair comparison really DC is just starting.
But how the hell do we keep jumping into completely different topics

I don't have a problem with it, discuss what you want but it's kinda funny. Like discussing child birth and somehow ending the conversation talking about how donald trump orchestrated 9/11.
